What is "process-physics", what does it deal with, sorry?
It's definitely a fringe physics, but my (perhaps old and faulty?) crackpot-meter hasn't gone off yet! (although regular physicists seem to dismiss it quite freely).
Reg's page doesn't seem to link to the old stuff any more like it used to:

I'm not a strong proponent of it or anything but I just liked the overall philosophical replacement of objects with change/relation as the core thing and also especially the idea that space itself could have self-organized out of something more primordial (ie less structured/dimensional).
Basically the world doesn't have matter at its base, but processes.
It's still an idea in progress of being understood for me, but seems quite cool stuff.
I heard it being mentioned that it might be linked with quantum field theory and somehow with string theory also, but I didn't yet understand how.
Maybe process physics is different tho.
Gosh, that reminds me of Wittgenstein's opening words in the TLP: "The world is the totality of facts, not of things".
Specifically the way that it explicitly avoids using syntactic information (ie anything symbolic (like how space is symbolic in the standard model)) and instead models the universe with only semantic (indeed ultimately self-referential) information instead. This is curiously similar to Neural-networks where the details of how it arrives at a result may be very well hidden in the details of the entire behavior of the network. A framework to think about bootstrapping the universe when there was no universe before is kinda a major component of the whole PP thing in my opinion.
This does seem to move the idea to a quite different realm than FP in my opinion. (maybe just a point of view thing?), but I imagine it more like some incredibly-infinitely parallel process like GOL/reaction-diffusion (without the virtual aspect we usually have with our normal computers) or even something more turing-machine-like (anything with turing-universal compute-capability can follow rules, right?)
I'm not trying to sound authoritative about this at all! I am certainly not a physicist (Visual Effects Artist/Pipeline/Teacher!), this is just something I took an interest in and I don't think it got anything approaching the reception that it perhaps could've had if there were a little more open-minded-ness and willingness to take conceptual leaps, in the surrounding academic community.
